I've done 8 projects so far with these lights and they've all worked great. I haven't actually submerged the battery in water, but it closes very tightly, so it's probably pretty waterproof. Lamps and cables are covered with a protective layer so that everything is in order. The remote worked well but the buttons were a little hard to press. Only warning: make sure you don't cut the wires between the battery pack and the headlights. You will never be able to remove the waterproof cover to access the cables. Great set of lights. I will buy many more.
